'William Becks' wa8wg@centurytel.net [op25-dev] op25-dev at yahoogroups.comJames, Can you also post your test.tsv file and elaborate on the specific P25 system that you desire to monitor? I have not had any issues with the RTL SDR on OP25 scope.py running under Ubuntu 14.04 using the following command outline to build my system. Let me know if you are running Ubuntu in VirtualBox on a Windows machine as there are a couple of additional pointers that I can pass along.

Everything compiles fine (this is a fresh install of Ubuntu 14.04) but when running scope.py I'm getting and undefined symbol error: (most recent call last): File "./scope.py", line 55, in <module> import op25_repeater File "/usr/local/lib/python2.7/dist-packages/op25_repeater/__init__.py", line 45, in <module> from op25_repeater_swig import * File "/usr/local/lib/python2.7/dist-packages/op25_repeater/op25_repeater_swig.py", line 28, in <module> _op25_repeater_swig = swig_import_helper() File "/usr/local/lib/python2.7/dist-packages/op25_repeater/op25_repeater_swig.py", line 24, in swig_import_helper _mod = imp.load_module('_op25_repeater_swig', fp, pathname, description) ImportError: /usr/local/lib/libgnuradio-op25_repeater.so: undefined symbol: _ZN8p25p2_vf12encode_dstarEPhPKi Searching around for this does not turn up anything really.
